The recall affects almost 863,000 vehicles in the United States and another 103,000 in Canada, Reuters reported.

Officials said the catalytic converters showed a deterioration of performance while on the road, according to Reuters.

The company said in a statement:

“We are advised that today’s EPA announcement reflects a new policy for announcing routine emissions recalls. This campaign has no safety implications. Nor are there any associated fines. This issue was discovered by FCA during routine in-use emissions testing and reported to the agency. We began contacting affected customers last month to advise them of the needed repairs, which will be provided at no charge.”

Reuters reported the company did not release how much the recall will cost, but the expense was accounted for in the fourth quarter of 2018.
